In the past twenty years, our knowledge on gas phase radical ion chemistry has been significantly improved due to the development of electron capture dissociation. Combined with soft ionization method, it has shown the technique can provide novel fragment ions for the structural elucidation of biomolecules, especially for protein characterization. This review aims to introduce fundamental aspects of electron capture dissociation mass spectrometry, as well as its applications in the analysis of biomolecules.
Key words: mass spectrometry, electron capture dissociation, gas phase ion chemistry, protein characterization
